IMPROVEMENT IN CANS FOR ROVING.

Specification forming part of Letters Patent No. 116,835, dated July 11, 1871.

To all whom Ait may concern:

Be it known that I, EZEA HAsKELL, of Dover, in the county of Stratford and State of New Hampshire, have invented a new and useful Iniprovent in Factory Sliver-Gan 5 and I do hereby declare that the following is a full, clear, and eX- act description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to a useful improvement in cans, called sliver-cans, used in cotton manufactories for receiving and discharging the cotton in the form of what is known as the sliver in the process of spinning. These cans (which are extensively used, numbering many thousands in some factories) have hitherto been made of tin, which, by the rough usage to which they are subjected, are soon destroyed or rendered useless. My invention consists in forming them, iii the main, of pasteboard or leather board, or the equivalent thereof, and providing them with wooden bottoms, top and bottom metallic dan ges, and a broad strengthening-band, the latter going around the can for about one-fourth of its height above the bottom, all being as hereinafter described and represented, thus rendering them lighter, cheaper, and more durable than'those made of tin or other metal. To save room, and for the purpose of enabling them to receive and discharge the sliver with facility, it is necessary that these cans should be cylindrical in form; consequently, my invention relates particularly to that or the common form and proportions.

The drawing, Figure l represents a can constructed according to my invention. In this eX- ample of my invention I use what is known as leather board, an article made of leather scraps combined with ber and other substances, which possesses many of the qualities of real leather, while it is vastly cheaper. This is formed into a cylinder with the edges riveted or cemented together, as seen in the drawing. Fig. 2 is a top view. Similar letters of reference indicate corresponding parts.

Around the top of the cylinder I place a double or single metallic ange, as seen in the drawing, where the sidepof the cylinder is broken away to show the construction.

A is the cylinder, and B shows the top ange or rim. C represents the riveted joint. Around the lower end of the cylinder I place a band, D, for the purpose of strengthening that portion. E represents the bottom, which is made of wood, to which the cylinder is attached by nails, or by screws, or in any other suitable manner. The rim B is attached by rivets, or is otherwise securedto thenpper end of thecylindci, and protects it from injury.

I do not confine myself to leather board in manufacturing these cans, although that is probably the material best adapted to the piupose on account of its clieapness, elasticity, lightness, and tenacity. They may be iliade of pasteboard properly prepared, or of other fibrous or textile fabrics, of leather and papier-mache?.

I claiin as new or improved manufacture, and of my invention- A roving-can, made substantially as specified, viz., of a leatherwboard or pasteboard body, a wooden bottom, metallic top and bottoni ianges, and a strengthening-band of leather board or the equivalent, all arranged and combined substantially as specified.

The above specification of my invention signed by me this 28th day of October, 1868.

EZRA HASKELL.
